United States Marine Corps Designated Marksman Rifle - Specifications

Specifications

There are several notable differences between the basic M14 and the DMR.

• Barrel: A 22 inches (560 mm) stainless steel, match-grade barrel by Krieger Barrels, Inc.
• Stock: McMillan Tactical M2A fiberglass stock. This particular stock features a pistol grip and a buttstock with adjustable saddle cheekpiece.
• Optics: An over-action MIL-STD-1913 Picatinny rail sourced from either GG&G Armament Arizona or Smith Enterprise, Inc. allows for the use of any optic compatible with the rail; this includes a rather large variety of military scopes and imaging devices. The most common scope used on the USMC DMR are TS-30.xx series Leupold Mark 4 day scopes, AN/PVS-10 or AN/PVS-17 night vision scopes, and Unertl M40 10× fixed power scopes.
• Muzzle device: Most DMRs utilize the traditional M14 muzzle device, although since deployment in 2001, some DMRs are now equipped with the OPS, Inc. 2-port muzzle brake, which is threaded and collared to accept an OPS-Inc. 12th Model sound suppressor.
• Bipod: A Harris S-L bipod is used on the USMC DMR.
